Changers and the Changed: Moral Aspects of Coming Out in Physical Education

In this paper we draw from interviews with four lesbian sportswomen and physical educators whose personal journeys inform us about the difficulties and rewards of challenging homophobia and heterosexism. Our co-participants discussed their life stories in terms of the interrelationships among sport, moral, and lesbian identities and their coming out process. Analyses of these narrations revealed three major themes associated with coming out in sport and physical education settings: integrity, compassion, and community. Each of these themes is discussed in terms of our co-participants' experiences and interpretations of moving from fear and isolation to a sense of community and empowerment.     

A typology of undergraduate students' conceptions of size and scale: Identifying and characterizing conceptual variation

The importance of “size and scale” in nanoscience and engineering has been recognized by both scientists and science educators. A solid understanding of this concept is key to the learning of nanoscience. Students, however, have been reported to have considerable difficulty grasping this concept; yet little is known regarding their state of understanding. To address this knowledge gap, we conducted a series of studies that were aimed at exploring the different ways students conceive of “size and scale” in the context of undergraduate nanoscience and engineering courses. Informed by Variation Theory of Learning (Marton and Booth, 1997), we identified four major categories (with two sub‐categories within each) of student conception—fragmented, linear, proportional, and logarithmic. These conception categories, together with the aspects of variation that characterize and distinguish them, are summarized in a typology. In addition to serving as a diagnostic tool to describe students' understanding, this typology can also be used to guide the development of instructional interventions that facilitate students to move toward a more sophisticated understanding of “size and scale.” © 2011 Wiley Periodicals, Inc., Inc.

Developing an instrument to characterise peer‐led groups in collaborative learning environments: assessing problem‐solving approach and group interaction

Collaborative learning is being used extensively by educators at all levels. Peer‐led team learning in a version of collaborative learning that has shown consistent success in science, technology, engineering and mathematics disciplines. Using a multi‐phase research study we describe the development of an observation instrument that can be used to assess peer‐led group learning. This paper illustrates the development of a classification system for peer‐led learning groups and an instrument based on this classification system. The instrument evaluates small learning groups on two important aspects of group learning: problem solving approach and group interaction style. We provide evidence of the factor structure of the two dimensions using both exploratory and confirmatory factor analysis. We also provide information about the reliability of the two scales as measured by the Cronbach's alpha coefficient. Data from a large peer‐led learning programme was used to conduct the factor analysis. Results from the factor analysis confirmed that the instrument is actually measuring two key characteristics of small learning groups: problem solving approach and group interaction style, characteristics that have been linked to effective functioning of the group and to the student learning outcomes. This instrument may be particularly appealing to practitioners (faculty members, those running small‐group learning programmes, etc.) because it is easy to use and it does not require extensive time for analysis.     

The cultural transition of Indigenous Australian athletes’ into professional sport

This article reports on a study that inquired into the journeys of sixteen Indigenous Australian athletes from their first touch of the footy to the Australian Football League (AFL) and National Rugby League (NRL) that identified two distinct stages of their journeys. These were: (1) the development of expertize and of a distinctly Aboriginal style of play from their first touch of a footy to around the age of thirteen and, (2) a process of cultural transitioning toward and into the AFL and NRL. This article takes an interdisciplinary approach to focus on the second stage of transitioning into the world of professional sport and sport as business. Identifying this as a process of cultural transitioning from local Aboriginal culture to the culture of professional sport provided insight into this transitioning process while illuminating the profound importance of culture in this process. It also helped identify the ways in which tensions between local approaches to ‘footy’ as play and cultural expression and professional sport as work, within the global culture of sport-as-business, were manifested in the challenges that the participants had to overcome. This article thus contributes to knowledge about Indigenous development of sporting expertize, of the specific challenges they face in transitioning into the global culture of commodified sport and how they succeed from a cultural perspective.

Differential genetic etiology of reading disability as a function of mathematics performance

In order to assess the etiology of reading disability as a function of mathematics performance, data from 168 monozygotic (MZ) and 127 same-sex dizygotic (DZ) twin pairs in which at least one member of each pair was reading-disabled were subjected to quantitative genetic analyses. MZ and DZ concordance rates for reading disability were computed for different levels of mathematics performance, and reading performance data were fitted to an extension of the basic multiple regression model for the analysis of selected twin data. Results of these analyses suggest that genetic factors may be especially salient as a cause of reading disability in children with borderline deficits in mathematics performance: thus, mathematics performance may be a valid dimension for diagnosing subtypes of reading disability.
